STATES WILFRIED KLAMROTH, OF NEW YORK, AN. Y.

STRING FASTENER.

Application filed April 17, 1920. Serial No. 374,550.

To all whom t may concern:

Be it known that I, WILFRIED KLAMROTH,

a citizen of the United States, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in String Fasteners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to string fasteners and its object is to provide a lacing hook which is arranged to grip and hold a string or lacing. Another object is to provide a simple, inexpensive and efficient device of this character which may be applied to shoes, gloves, corsets or other articles with which a lacing is used. More specifically, its object ig to provide a spiral spring in a lacing hook which is so arranged that the string in being placed in the hook may be drawn in between adjacent convolutions of the spring and be held thereby.

These and other objects of the invention will be described in the following specification, the novel features of which will be 25 set forth in the appended claim.

Referring to the drawings:

Figure 1 is a perspective view of the upper portion of a shoe with a pair of my improved string fasteners thereon.

Figure 2 is a plan view of one of the hooks and string fasteners shown in Figure 1.

Figure 3 is a sectional side elevation of a string fastener or hook which is made according to and embodies this invention, and in this figure a part of the article to which it is aiiixed is also shown in section.

Figure 4 is a sectional front elevation of a device of modified construction which also embodies this invention.

Like characters of reference designate corresponding parts in all the figures of the drawings.

designates an article to which the string fastener is aflixed, and 11 is the string or lacing which is to be fastened thereby. The

hook shown in Figures 1, 2 and 3 is designated generally by the reference numeral 12 and comprises a base 13, a flange 13A which projects through and is bent under the article to aflix the hook thereto, the bracket 14 50 extending upwardly from one side of the base 13 and an internally concave part 15 which is substantially parallel with the base 13.

2,0 is a short spiral spring, the diameter of which is approximately the same as the base 13. This is inserted between the base and the part 15 and its upper end is fastened to the part 15 near the bracket 14 in some suitable manner as by being soldered thereto, as shown at 2l. The other end of this spring projects rearwardly through the bracket 14 as at 22. Intermediate its ends and opposite the bracket 14 adjacent convolutions of the spring 2O are bent to iiare apart as shown at 23 to form a gateway for the easy insertion of the string.

The operation of this device is obvious. It may be seen that when the string 11 is drawn into the hook, it will enter between adjacent convolutions of the spiral spring and its insertion between these convolutions is facilitated by the flare formed by the outwardly bent parts 23 of the spring. As the string is pulled back between these convolutions of the spring it will be securely gripped thereby to an extent which will form a secure anchorage and prevent the string from slipping. 'Ihe string shown in Figure 1 is a round shoe lace but the device is equally applicable for use with flat strings or laces.

When the shoe lace, for example, is pulled into a pair of these fasteners 12 near the upper part of the shoe, it will be held thereby without being tied although of course the end portions of the Strings may be tied in a bow or otherwise if so desired.

The spiral spring may be held in the hook in other ways if desired. For example, in the construction illustrated in Figure 4, the end convolutions of the spring 2OA are substantially parallel. The edges of the base 13 are crimped over the lower convolution of this spring as Shown at 13A and the edges of the part 15 are crimped over the upper con- 95 volution of the spring as shown at 15A. This ligure has been added for the purpose of showing that I do not intend to limit imyself to a specific form of construction, and in fact I intend no limitations other than those imposed by the appended claim.

What I claim is:

A string fastener comprising a pair O spaced members joined at one side thereof, a spiral spring interposed between said members, said spaced members having their edges` crimped around the end convolutions of the spring, adjacent eonvolutions of the spring l0 being bent to diverge opposite the slide at which the spaced members are joined.

In Witness whereof, I hereunto set mv hand this 12th day of April, 1920.

WILFRIED KLAMROTH.
